【摘要】 珊瑚矿区钨锡矿床成矿地球化学作用多期多阶段的特点,突出表现为平面上的顺向分带。以热液源为中心,向北西依次产出钨锡石英脉矿床、钨锑萤石石英脉矿床和含钨角砾石英脉矿床。气成热液地球化学作用导致钨锡石英脉矿床垂向上表现为逆向分带,W、Sn、F等成为矿体前缘指示元素,而Cu、Pb、Zn等成为矿体中下部指示元素。更多还原

【Abstract】 The multi-phase and multi-stage characteristics of the geochemicalprocess of the formation of the Shanhu W-Sn deposit strikingly shows analong-directional zoning in horizontal plane, Centring around hydrothermalsource towards NW, successively occurred the W-Sn quartz vein deposit,W-Sb fluorite quartz vein deposit and W-bearing brecciated quartz veindeposit. Pneumatolytic-hydrothermal geochemical process resulted in areverse vertical zoning in the W-Sn quartz vein deposit. It is indicatedthat W, Sn, F ect. are frontal indicatop elements of orebody, whereas Cu,Pb, Zn ect. are mid-lower ones.更多还原
